HP 182C - Table 1-2. Reference Designators and Abbreviations

General
Information
Model
182C
1-30.
Waveform
photography of the Model 182C display
can be accomplished with the Model
10367A Camera
Adapter, The adapter fits into the Model 182C bezel,
replacing the
contrast filter, for use with the Model 1
95A
and Model 1
97A Oscilloscope Cameras.
1 31. A
Horizontal Gain
Calibrator, HP Model 10411A,
facilitates rapid
and accurate
calibration of the horizontal
deflection factor of the Model 182C.
Also
available is a
Service
Extender, HP Model 10133A, which is
useful for
troubleshooting the
complete power
supply module when
removed from the oscilloscope
mainframe.
1-32. For case of calibration and
maintenance, the HP
Model 10407 A Plug-in
Extender can be obtained. It
provides
for removal of the vertical
and
time
base plug-ins
from the
oscilloscope mainframe and exposes components
and adjustments
of
the
plug ins for servicing.
1-33, Blank plug-ins are available
for
use
with the Model
182C. These units fit into the
oscilloscope vertical and
time base
compartments and provide the
necessary inter-
face
connections and
operating power for user
designed
vertical
amplifier and/or time base
circuitry. Refer to
Section IV
for the
operating power available from the
oscilloscope
mainframe. The
following units are available:
HP Model 10408A Vertical Blank Plug-in, HP Model
10409A Horizontal Blank Plug-in. and HP
Model 10410A
Dual
Blank Plua-in.
1 34. A metallic mesh contrast filter which
functions
as
an RFI shield is available for the
Model
182C.
The mesh
filter, HP Part No. 00182-62701,
is directly interchang-
able with the standard blue plexiglas filter. When installed,
the metallic mesh filter
is electrically grounded
to the
oscilloscope chassis, thereby furnishing
RFI shielding.
1-35.
Cameras,
probes, viewing hoods, terminations and
other accessory
items arc available for specialized require-
ments. Information
on these and the above described
accessories may be obtained from HP Sales/Service Offices
listed in the rear of this manual.
